c# - Deleting Duplicates From An Array -


i have code load text file , save array. array contains list of numbers of numbers being duplicated. in code first loop through array , replace duplicated numbers -1. plan on deleting -1 values array. remaining array values (non duplicates) copied on new array outputted.

however keep getting error when attempt delete -1 values array (see code below). don't know why happening if knows please let me know!

p.s. school project can use loops , if statements, not things linq or foreach, etc.

public partial class form1 : form {     //global variable     int[] original;      public form1()     {         initializecomponent();     }      //exit application     private void mnuexit_click_1(object sender, eventargs e)     {         this.close();     }      //load file     private void mnuload_click_1(object sender, eventargs e)     {         //code load numbers file         openfiledialog fd = new openfiledialog();          //open file dialog , check if file selected         if (fd.showdialog() == dialogresult.ok)         {             //open file read             streamreader sr = new streamreader(fd.openfile());             int records = int.parse(sr.readline());              //assign array sizes             original = new int[records];              //go through text file                           (int = 0; < records; i++)             {                 original[i] = int.parse(sr.readline());             }         }     }      private void btnoutput_click(object sender, eventargs e)     {         //store original array         string output = "original \n";          //output original array         (int = 0; < original.length; i++)         {             output = output + original[i] + "\n";         }          //create temparray         int[] temparray = new int[original.length];          //set temparray equal original array         (int = 0; < original.length; i++)         {             temparray[i] = original[i];         }          //duplicate number counter         int counter = 0;          //loop through entire array         (int = 0; < temparray.length; i++)         {             (int j = + 1; j < temparray.length; j++)             {                 //replace duplicate values '-1'                 if (temparray[i] == temparray[j])                 {                     temparray[j] = -1;                     counter++;                 }             }          }          //set size of original array         original = new int[original.length - counter];          //remove -1 values          //index counter         int index = 0; //error starts         (int = 0; < temparray.length; i++)         {              if (temparray[i] != -1)             {                  original[index] = temparray[i];                 index++;             }         } //error ends         //final output -- new array         output = output + "original without duplicates\n";          (int = 0; < original.length; i++)         {             output = output + original[i] + "\n";         }         lbloutput.text = output;          }     } }

reverse line temparray[i] = original[index]; original[index] = temparray[i];

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
